少年儿童眼外伤术后无晶体眼的接触镜矫正

目的探讨少年儿童单眼外伤术后无晶状体眼的接触镜(CL)矫正方法和临床效果.方法观察81名少年儿童眼外伤术后患者的眼部改变,并根据其屈光状态的变化、对侧眼的状态及其生活的实际需要,选择验配了软性接触镜(SCL)、托力克软性接触镜(TSCL)、透气性硬性接触镜(RGPCL)、加虹膜色彩的非透气性硬性接触镜(PMMA虹彩片)和软、硬组合型镜片系统(Piggyback CL),并比较视力矫正效果.结果与对侧健眼比较,外伤术后眼角膜曲率半径值显著改变,角膜散光度明显增加.52眼选用SCL和TSCL,矫正视力与框架眼镜比较无明显差异;22眼选用RGPCL,4眼选用PMMA虹彩镜,3眼选用Piggyback CL,三种镜片矫正视力比框架眼镜明显提高.PMMA虹彩镜和Piggyback CL用于外伤后角膜白斑、术后无晶状体、虹膜严重损伤眼,除显著提高视力外,还明显改善了羞明症状和眼外观.结论在严格的医疗化管理下,利用CL矫正少儿眼外伤术后无晶状体眼的高度屈光不正、屈光参差,恢复双眼视觉是安全、有效的.硬性接触镜(HCL)的视力矫正效果明显优于SCL.

Contact lens correction for youngsters following traumatic aphakia postoperatively

Objective To assess the contact lens fitting and its clinical effects for the youngsters following traumatic aphakia postoperatively. Methods 81 patients (3-19years) with single traumatic aphakia were fitted postopera-tively with soft contact lens (SCL), toric soft contact lens (TSCL), rigid gas-permeable contact lens (RGPCL), PMMA lens with iris color (IC-HCL) and Piggyback Lens respectively. The corrected visual acuity with varied contact lenses and spectacles were compared. Results There was significant changes in corneal radius and corneal astigmatism in the traumatic eyes compared with normal eyes. Fifty- two (52) eyes were fitted with SCL and TSCL and there was no difference in visual acuity between the SCL and spectacle correction. Twenty- nine (29) eyes were fitted RGPCL, IC-HCL and Piggyback CL and the visual acuity with HCL correction was much better than that with spectacle correction. IC-HCL and Piggyback CL also achieved satisfaction within cosmetic effects and reduction of phosphobia. Conclusion It is safe and effective to use CLs in youngsters' traumatic aphakia with high refractive error and anisometropia after surgery when there is strict medical administration. Corrected visual acuity of HCL is showed better effects than SCL.
